Chapter 17 501 P17.6 It is easiest to solve part (b) first: (b) The distance the sound travels to the plane is dh hh s =+ F H G I K J = 2 2 2 5 2 . The sound travels this distance in 2.00 s, so d h s == = 5 2 343 2 00 686 ms s m bg a f . giving the altitude of the plane as h 2686 5 614 m m af . (a) The distance the plane has traveled in 2.00 s is v h 200 2 307 . s m a f . Thus, the speed of the plane is: v 307 153 m 2.00 s ms . Section 17.2 Periodic Sound Waves P17.7 λ × = v f 340 60 0 10 567 31 s mm . . *P17.8 The sound speed is v ° ° = 331 1 26 346 C 273 C (a) Let t represent the time for the echo to return. Then dv t × = 1 2 1 2 346 24 10 416 3 ms s m .. (b) Let t represent the duration of the pulse:
